By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away.

A team of researchers at the University of California, Los Angeles (UCLA) are building an advanced scientific instrument unlike any other ever built before, with the aim to study some of the oldest galaxies in the universe.

An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star.

An astronomer has discovered a faint "satellite galaxy" that is the lowest-mass object ever detected 10 billion light years away.

NASA said on Thursday that astronomers have found evidence for two extrasolar planets using Hubble Space Telescope data from 1998.
